With the rapid development of economy and the enhancement of productivity of our country, many problems are also followed. Coal chemical enterprises are the major consumer of water who produce huge volumes of wastewater during the production. The wastewater is mainly divided into brine wastewater and organic wastewater, the brine wastewater mainly come from circulating water, desalination stations, boilers and chemical cleaning. At present, for the treatment of chemical industry wastewater, evaporation crystallization technology is generally used to treat high-salt wastewater. But in recent years, with the improvement of productivity, volumes of wastewater discharge increased, leads to growth production of coal chemical crystalline salt with its characteristic of soluble in water, which caused secondary pollution. Therefore, how to achieve zero discharge of coal chemical wastewater and re-utilization of concentrated brine are obviously important.

　　For chemical concentrated brine, Rightleder adopts the process with the treatment by Wastout Microwave Multi-effect Filtration System at first, followed by R-MF Filter and Self-cleaning Filter. After these preliminary treatments, the water quality meets the inlet requirements of UF unit, filtered by UF then enter the Curved Micro-conducting Force System, and the concentrated water is fed into the Neterfo Ultimate Separation Reverse Osmosis Equipment for in-depth treatment. The effluent quality meets the reuse standard

　　In this process, the Wastout Microwave Multi-effect Filtration System has the advantages of small area and low project cost, and can reduce the contents of TOC, chromaticity, metal and hardness. While broadening the field of use, it can withstand the impact of high load, together with the unique water distribution system to ensure the treatment effect. The Curved Micro-conducting Force System improves the membrane performance by 10-20%, has a flexible operation setting of recovery rate, and the low energy consumption is suitable for front-end desalination treatment. Rightleder’s Neterfo Ultimate Separation Reverse Osmosis Equipment is designed specifically for hypersaline water concentration, can reach operating pressure by 120 bar, which is suitable for brine and seawater with high salinity, and high-multiple concentration and treatment of various high concentration waterborne materials. The optimized component structure of the membrane element adopts a strong and durable high-pressure separation diaphragm to ensure that it can withstand high operating pressure, and the operating cost per ton of water is about 30% lower than that of traditional equipment.
